Account debited

Yesterday 25.01.2016 I noticed an amount of R119.99 had gone of my account. I phoned the bank to ask them who DTH is. They gave me a number for Stratcol. I phoned them and according to Jane at reception they do not deal with individuals only with companies and gave me the number for Prestige Group to query the debit.<br> I phoned Prestige and spoke to Nisa, she could not give me any details but that she will get her manager to contact me.<br> I tried phoning again and the telephone is on voicemail and no space to leave a message. This totally smells like ***** to me. Please can someone investigate these companies. Where did they get my bank account details to debit my account?
